SEWER-TRAP.

SPECIFICATION forming part of Letters Patent No. 505,302, datedSeptember 19, 1893.

Application filed April 26, 1893- Serial No. 471,883. (No model.)

To all whom it may concern.-

Be it known that 1, PETER STANDER, a citizen of the United States,residing at Belleville, in the county of St. Clair, State of Illinois,have invented a new and useful Improvement in Sewer-Traps, whichimprovement is fully set forth in the following specification andaccompanying drawing.

Myinvention consists of a sewer trap formed of a pipe with an invertedbell, the latter opening into the sewer from below, whereby its mouthdips into the fluid or sewage, and is accordingly sealed.

It also consists of novel means for sustaining the bell, as will behereinafter set forth.

The figure represents a vertical section of a sewer trap embodying myinvention.

Referring to the drawing: A designates a sewer, in the side wall ofwhich, near the bottom thereof, is an opening B, which receives a sewerpipe 0. On the end of said pipe, within the sewer, is an inverted bellD, which dips into the fluid or sewage so that the mouth or dischage endof said bell is sealed and the gas is prevented from entering the bell,and consequently the pipe 0.

In order to support the bell and sustain the same against pressure ofthe flowing sewage or superimposed weight, the inner wall of the seweris formed with a recess E, which extends downward from the opening B,and receives a portion of the inner wall of the bell. The lower wall Fof said recess has the lower edge of said portion of the wall of thebell resting thereupon, whereby the bell is prevented from dropping orbeing forced downwardly or laterally.

Having thus described my invention what I claim as new, and desire tosecure by Letters Patent, is-

A sewer having the opening B in its side, and the recess E in its innerface below and communicating with said opening, in combination with thepipe 0 fitting in said opening, and having on its end within the saidsewer, the inverted bell D, the latter having a portion thereof in saidrecess and supported on the lower wall thereof, substantially asdescribed.
